How to apply IFFT in Matlab?

Hi,

I am new to Matlab.

I have frquency domain data, in which, I have 2 sets of 31 numbers at 1.5 GHz frequency. I imported all the data ( 3 coloums and 31 rows) in microsoft excel. I want a code through which i can read this data in Matlab and apply IFFT and convert it into Time domain.

I have no idea how to do that. So can someone please share any link or tutorial with me or if can write me here.

Thanks in advance.

You have to have data continuously from 0 Hz to your highest frequency (apparently about 1.5 GHz), or the inverse Fourier transform cannot be made to work.

Thanks madhan,

Could you please elaborate it a little bit. How can i import my excel file and then IFFT?
